BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to novel solid pharmaceutical compositions and processes for the bulk production of said compositions. This invention also provides methods of using the pharmaceutical compositions in the treatment of cancer.

Background of the Invention

In general, solid pharmaceutical compositions comprise a pharmaceutically active ingredient, such as a small molecule, admixed with pharmaceutically acceptable excipients in amounts appropriate to maintain the original activity of the active ingredient. These compositions are typically delivered to patients in the form of tablets or capsules.

Examples of particular active ingredients can be found in U.S. Pat. No. 7,572,784, US Publication No. 2008/0045501, US Publication No. 2008/0167292, and U.S. Application No. 61/306,047, filed Feb. 19, 2010, hereby incorporated by reference in their entirety, which disclose compounds that inhibit Aurora kinase enzymes. These applications additionally disclose methods for the preparation of these compounds, pharmaceutical compositions containing these compounds, and methods for the prophylaxis and therapy of diseases, disorders, or conditions associated with overexpression and/or amplification of Aurora kinases, including, but not limited to, cell proliferative disorders such as cancer.

Important considerations during the manufacturing of solid pharmaceutical compositions include preserving the crystal form of the active ingredient and maintaining the active ingredient's chemical and physical stability. Manufacturers generally target a 2- to 3-year shelf life for pharmaceutical compositions.

Thus, there is a need to develop solid pharmaceutical compositions that are stable and have favorable bioavailability. In particular, there is a need for solid pharmaceutical compositions comprising Aurora kinase inhibitors.

DESCRIPTION OF THE INVENTION

The present invention provides methods for preparing the solid pharmaceutical compositions described herein. These methods offer an alternate approach to processing wet granulation based formulations that require a buffer for bioavailability as compared to prior art methods. It has been determined that the order of addition of excipients during the granulation process affects the drug product's dissolution when stored for stability studies.

In another aspect, the invention provides pharmaceutical compositions that may be prepared by such methods, comprising the active ingredients, buffers and additional excipients as described herein.

In yet another aspect, the invention provides methods for treating disorders using the pharmaceutical compositions as described herein.

The patent and/or scientific literature referred to herein establishes knowledge that is available to those with skill in the art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention relates. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, the preferred methods and materials are described herein. The issued patents, applications, and references that are cited herein are hereby incorporated by reference to the same extent as if each was specifically and individually indicated to be incorporated by reference. In the case of inconsistencies, the present disclosure, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and are not intended to be limiting.

DEFINITIONS

The term “active ingredient” is used herein to mean a component of a pharmaceutical composition that is pharmaceutically or physiologically active.

The term “pharmaceutically acceptable excipient” is used herein to refer to a material that is compatible with a recipient subject, preferably a mammal, more preferably a human, and is suitable for delivering an active agent to the target site without terminating the activity of the agent. The toxicity or adverse effects, if any, associated with the excipient preferably are commensurate with a reasonable risk/benefit ratio for the intended use of the active ingredient. Classes of pharmaceutically acceptable excipients include, but are not limited to, surfactants, binders, disintegrants, lubricants, glidants, fillers, and buffers.

The term “about” is used herein to mean approximately, in the region of, roughly, or around. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 10%.

As used herein, “w/w %” is used to mean by weight as a percentage of a total weight that is used as the basis for calculating the weight percentage of an individual component. By way of example, for a bulk composition, the w/w % of an individual component may be calculated as a percentage of the total weight of all of the components of the bulk composition. By way of another example, for a single oral dosage form, the w/w % of an individual component may be calculated as a percentage of the total weight of all of the components of the single oral dosage form. For example, when the single oral dosage form is a coated tablet, the total weight may be the total weight of all the components of the coated tablet including the coating(s). Alternatively, the total weight may be the total weight of all the components of the tablet not including the coating(s)

As used herein, the term “comprises” means “includes, but is not limited to.”

As used herein, a “subject” is preferably a bird or mammal, such as a human, but can also be an animal in need of veterinary treatment, e.g., domestic animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, sheep, fowl, pigs, horses, and the like) and laboratory animals (e.g., rats, mice, guinea pigs, and the like).

As used herein, “treating” or “treatment” means prevention, partial alleviation, or cure of a disease, disorder or condition.

As used herein, “therapeutically effective amount” is meant to describe an amount of a compound, composition, medicament or other active ingredient effective in producing the desired therapeutic effect.

As used herein, the term “Aurora kinase” refers to any one of a family of related serine/threonine kinases involved in mitotic progression. A variety of cellular proteins that play a role in cell division are substrates for phosphorylation by Aurora kinase enzymes, including, without limitation, histone H3, p 53, CENP-A, myosin II regulatory light chain, protein phosphatase-1, TPX-2, INCENP, survivin, topoisomerase II alpha, vimentin, MBD-3, MgcRacGAP, desmin, Ajuba, XIEg5 (in Xenopus), Ndc10p (in budding yeast), and D-TACC (in Drosophila). Aurora kinase enzymes also are themselves substrates for autophosphorylation, e.g., at Thr288. Unless otherwise indicated by context, the term “Aurora kinase” is meant to refer to any Aurora kinase protein from any species, including, without limitation, Aurora A, Aurora B, and Aurora C, preferably Aurora A or B. Preferably, the Aurora kinase is a human Aurora kinase.

The term “Aurora kinase inhibitor” or “inhibitor of Aurora kinase” is used to signify a compound having a structure as defined herein, which is capable of interacting with an Aurora kinase and inhibiting its enzymatic activity. Inhibiting Aurora kinase enzymatic activity means reducing the ability of an Aurora kinase to phosphorylate a substrate peptide or protein. In various embodiments, such reduction of Aurora kinase activity is at least about 50%, at least about 75%, at least about 90%, at least about 95%, or at least about 99%. In various embodiments, the concentration of Aurora kinase inhibitor required to reduce an Aurora kinase enzymatic activity is less than about 1 μM, less than about 500 nM, less than about 100 nM, or less than about 50 nM.
